For me it would be a tie between getting the Suicide Missionary Achievement in Gears of War 2,and the Hardened War Hero in World at War.

Press Start - Simpsons Game.

Honestly, Beating Raam on Gears Insane!

Unstoppable World Serpent - Too Human. 20 attempts on that bastard!

But according to True Achievements, it Big Cheese of the South Seas on Hexic. 4.71 ratio.

CoD: WaW - Heart of the Reich on veteran.

At the Flak 88s it was just a horrible combo of insane grenade spam, infinite highly-accurate enemies and rubbish cover.
The majority of my attempts ended up being run out of the tunnel, get almost killed, take cover to try and regain some, get surrounded by 7 grenades (no exaggeration, I counted the bloody things), die since I couldn't escape, repeat.

The annoying thing is that I swear they've reduced the number of grenades since I done it [in the launch week]. I've ran through it since then and I was only coming across two grenades, sometimes three at once.

Dead Space 2 on the hardest difficulty. Beat the game with almost zero ammo, no checkpoints, extremely tough enemies and, oh yeah, 3 saves. I died on chapter 7 and had to restart the entire game. It is painful.

According to Trueachievements, it's pretty much a tie between Completist and Master of Chaos for Dynasty Warriors 6, with Fleet Depleter from Earth Defense Force: Insect Armageddon coming in third.

Though, those are more grind based achievements than anything.

mrj3d

07-01-2012, 01:36 AM

Completing Mass Effect on Insanity took some trial and error. I also just got the 1000 in Blue Dragon, which I'd say was pretty tough. Some achievements were actually hard, some were very long grinding.

Unstoppable World Serpent - Too Human. 20 attempts on that bastard!

I tried for that...once. Never again. :p

According to TA (last I checked), it was beating Arcade mode on MAX with no continues, on MK vs DC. Though that was pretty easy, definitely easier than the Unstoppable achievements despite whatever the ratios may say.

Mile High Club, or beating Call of Duty:World at War on veteran. Those last missions were insane with those unlimited grenades and spawns.

07-01-2012, 06:42 AM

It's getting harder and harder to decide which achievement was the hardest, because in hindsight they all seem far easier than I'm sure they did at the time. Plus, I've completed quite a few "harder" games now. I reached lvl 20 in Game Room, completed Too Human, achieved platinum in Naughty Bear and Prototype, gotten a pearl-flower in Hexic HD, became Kingpin in Saints Row an Saints Row 2, bred fish in Aquazone...and many more. At 190 completed games, its hard to choose one.

Toams07

Toughest was probably Marathon from Trials HD

Genesis x360a

07-01-2012, 01:57 PM

Probably Extreme Solider from Lost Planet. I've played and completed quite a few difficult/hard games so its hard to say which but Extreme Solider stands out in my mind as being one of the hardest when I try to think :p

At the moment, mine would have to be the Bladder Of Steel achievement on Rock Band 2. It took only four tries, but two of those ended with under 8 songs left to go. (Batteries died/time constraint.)

I have a lot of achievements that were time consuming but not necessarily hard like in Blue Dragon, Saints Row, and FF13.
According to TA the achievement with the highest ratio I have is 'Level 20' in Game Room at 8.73.

The achievement that actually felt was the hardest that I have is 'Platinom Nom Nom' from Kinect Adventures. Between the problems with Kinect not picking you up occasionally and then having to get enough coins to get the Platinum on each level is quite difficult.

TA ratio's aren't that accurate, (Once again that MK v DC one I have being 6.14 is just silly), but that's probably the best example. A lot of people just got 80g of game room and moved on taking no interest in it's difficulty. So it's no wonder it didnt feel the hardest. Ive attempted achievements with a TA ratio less than 3 that were harder than the MK v DC one.

07-02-2012, 01:51 PM

Hard to pick one.
Halo Reach on Solo Legendary. Mostly grand but Long Night of Solace and Pillar of Autumn took me an hour and a half + each.

Annual in Halo 3. Simple enough until you get to the ghosts, then you keep ramming off each other by accident. Overall took us two hours.

Contingency (MW2) on veteran, because of the sub timer alone.

Again, Mile High Club.

The entire WaW campaign on Veteran.

I still don't have the last two.

EliteShadowMan

07-02-2012, 02:34 PM

I know i've done quite a few hard achievements, but right now i'm having a hard time remembering. I can only really think of time consuming achievements.

Mile High Club - This one took me about 2-3 hours of constant trying, and a lot of swear words. In the end i finally got it.

A Monument To all Your Sins - Beating Halo: Reach on Legendary alone. What a pain in the ass the game was for me on the final 2 missions.

The 10 wins in a row on Mortal Kombat. Can't remember the name, but i'm glad i was getting a bunch of decent players and not any good ones.

Getting all the mosaic pieces in FIFA 12 Euro DLC is slowly grinding me down! 38 left to get! I'm playing every game too, no cheats. 4 minute halves on professional though so pretty easy. :)

Well my highest cheev on TA is Heavyweight (GRAW) but it wasnt hard at all, just time consuming. I would think finishing Gears 1 on Insane was probably the hardest, the last boss was a right pain in the rear

07-02-2012, 07:04 PM

Just done 'The Shadows Rushed Me' on Max Payne 3. Thats my hardest, but other tough ones were 'Aperture Science' on Orange Box + 'To Explore Strange New Worlds' in Mirrors Edge. I was also pretty pleased with 'Strings of Steel' in The Gunstringer, I was the second on ta to unlock it and it remains on of my best ta score achievements, It has a ratio of 14.05!

The fact that it spawned me back to the mansion everytime I died made it really annoying and time-consuming.

HEXSNAKE

07-03-2012, 06:53 PM

Loads of disgusting hard one's out there. But I remember searching for an ice age to find the last templar in Assassins Creed - Personal Vendetta. I remember seeing him in the distance and I jumped off my horse and ran straight at him. He was dead in a second. It was a good day.

CoregBlue1

07-03-2012, 06:55 PM

Good idea, i searched for mine according to TA. Funnily enough the cheevo with the highest ratio was the one i posted about on page 1:

without checking it i am pretty certain this is from a bullethell, if not cave, game. those probably fill out the top list on every site with achievements like star ocean TLH: 100% battle trophies.

my hardest would be Mr. Perfect on MegaMan 10.

Annual in Halo 3. Simple enough until you get to the ghosts, then you keep ramming off each other by accident. Overall took us two hours.

lol i would have to agree, i did it with some members from the site. that was actually mindblowing to me, after beating the campaign 100+ times on different difficulties i never saw that area down there with those ghosts. i think they only show up if you are on-par with getting the challenge with 4 people.

and ya funny you mention that bit, it was by far one of the funniest achievements i ever tried to get. one person falls off the edge and we all have to restart, and usually nobody wanted to admit to fucking us up lol! i remember i got stuck AS checkpoint triggered, i was in the back of the line so everybody made it but me. it reloaded the checkpoint like 10+ times, 10+ times of me falling into the obyss and everyone telling me "BOOST MOAR!" lol, that end sequence is a bitch with 4 people on ghosts.

Bobalue

07-04-2012, 03:48 PM

Mine is from Guitar Hero III hands down. That game took years of practice to perfect. Probably would have to be for scoring 750,000 points in a solo song (Now That's Impressive) or beating TTFAF on Expert (The Inhuman Achievement).

Apart from that, it would have to be beating CoD:WaW on Veteran.

Another tough one was "Beating tough competition" in NHL 08.

Iceskater101

07-04-2012, 03:51 PM

I guess my toughest achievement was completing Halo Reach on Legendary by myself. I have gotten other harder achievements, but this one stands out the most because I was so frustrated by the campaign. I was so proud when I got this.

Not sure it was the toughest... but definitely ranked up there was "If they came to hear me beg" from Halo: Reach. The Achievement where you had to assassinate an Elite to survive a fall that would've killed you.

My number 2 - Beating Dead Space 2 on Hardcore.

07-08-2012, 02:09 AM
